bite-keeper

Build Status codecov

The DAI Stablecoin System incentivizes external agents, called keepers, to automate certain operations around the Ethereum blockchain.

bite-keeper is one of the simplest keepers. It constantly monitors a Tub contract looking for unsafe cups and bites them the moment they become unsafe. Ultimately, it should take into account the profit it can make by processing the resulting collateral via bust and only waste gas on bite if it can make it up by subsequent arbitrage. For now, it is a dumb keeper that just bites every cup that can be bitten.
